r/learnjavascript on Reddit: JavaScript String method: Split, Concat, and Join
July 27, 2023 -
I'm doing a code wars practice on JavaScript involving the JavaScript methods split(), concat(), and join(). This is the problem:
Implement a function which accepts 2 arguments: string and separator.
The expected algorithm: split the string into words by spaces, split each word into separate characters and join them back with the specified separator, join all the resulting "words" back into a sentence with spaces.
For example:
splitAndMerge("My name is John", " ") == "M y n a m e i s J o h n" splitAndMerge("My name is John", "-") == "M-y n-a-m-e i-s J-o-h-n" splitAndMerge("Hello World!", ".") == "H.e.l.l.o W.o.r.l.d.!" splitAndMerge("Hello World!", ",") == "H,e,l,l,o W,o,r,l,d,!"This is the code I've made thus far:
function splitAndMerge(string, separator) {
let char = string;
let cap = char.split("");
let combo = cap.join(" ");
return char.split("").join(" ");
}It splits it up but I don't know how to get it to produce the final results of having each separator be different. Can anyone help?

Hopefully this solution and its comments are helpful: https://codepen.io/pigparlor/pen/gOQBXOd?editors=0010 function splitAndMerge(string, separator) { const words = string.split(' '); // e.g. ['My', 'name', 'is', 'John'] const charsJoined = words.map(word => word .split('') // e.g. [['M', 'y'], ['n', 'a', 'm', 'e'], ['i', 's'], ['J', 'o', 'h', n']] .join(separator) //e.g. ['M-y', 'n-a-m-e', 'i-s', 'J-o-h-n'] ); const wordsJoined = charsJoined.join(' '); // e.g. 'M-y n-a-m-e i-s J-o-h-n' return wordsJoined; }

The join method can take the separator as an argument, like join('.'), for example. So, just use join(separator)

With JavaScript’s String.prototype.split function:
var input = 'john smith~123 Street~Apt 4~New York~NY~12345';
var fields = input.split('~');
var name = fields[0];
var street = fields[1];
// etc.

According to ECMAScript6 ES6, the clean way is destructuring arrays:
const input = 'john smith~123 Street~Apt 4~New York~NY~12345';
const [name, street, unit, city, state, zip] = input.split('~');
console.log(name); // john smith
console.log(street); // 123 Street
console.log(unit); // Apt 4
console.log(city); // New York
console.log(state); // NY
console.log(zip); // 12345You may have extra items in the input string. In this case, you can use rest operator to get an array for the rest or just ignore them:
const input = 'john smith~123 Street~Apt 4~New York~NY~12345';
const [name, street, ...others] = input.split('~');
console.log(name); // john smith
console.log(street); // 123 Street
console.log(others); // ["Apt 4", "New York", "NY", "12345"]I supposed a read-only reference for values and used the const declaration.
Enjoy ES6!

1. Split - (Split a string into an array of substrings)
var str = "This is a string";
var str = "This is a string";
var res = str.split(" ");
console.log(res);It is important that split gives back an array with the string chunks.
2. Substr - (Extract parts of a string)
var str = "This is a string";
var res = str.substr(1, 4);
console.log(res);3. Substring - (Extract characters from a string)

var res = str.substring(1, 4);

I think you want to use substring() (read more here: https://www.w3schools.com/jsref/jsref_substring.asp)
For example,
var str = "Hello world!";
var res = str.substring(1, 4);
would be equivalent to this Python code:
str = "Hello world!"
res = str[1:4]
res would be 'ell'. The start and end indices work the same as in Python (includes the start index, goes through but not including the end index.
